## Discrepancy

(CAN) DURING CLIMB THE CREW WERE UNABLE TO RETRACT THE NOSE GEAR AND HAD THREE RED GEAR UNSAFE DOORS WHEN GEAR SELECTED UP. AFTER SELECTING GEAR DOWN 3 GREEN WERE OBSERVED. THE CREW DECIDED TO RETURN TO BASE AND DECLARE AN EMERGENCY. THE FLIGHT LANDED WITHOUT INCIDENT. DURING TAXI THE AIRCRAFT WAS PULLING LEFT AND NEEDED CONSTANT RIGHT-HAND PRESSURE TO TAXI STRAIGHT. MAINTENANCE TROUBLESHOOTING DISCOVERED CODES INDICATING BOTH NOSE WHEEL STEERING RVDT`S OUT OF RIG. THE RVDT`S HAVE BEEN RIGGED WITH MULTIPLE GEAR SWINGS AND STEERING/CENTERING CHECKS CARRIED OUT AND NO FURTHER ISSUES NOTED.
